Aphelopus zaifui Olmi, Chen & Liu sp. nov. urn:lsid:zoobank.org:act: 730357C7-2449-42BE-99A6-6DBFFE97DC67 Figs 7, 8D Diagnosis Male with head black, except mandible testaceous; notauli complete (Fig. 7B) or almost complete (Fig. 7F), posteriorly separated; distivolsella in the form of a long straight rod (Fig. 8D); basivolsella long and narrow, with distal apex very widened (Fig. 8D). Etymology The species is named after the late Prof. Zaifu Xu (SCAU), a famous specialist of Chinese Dryinidae. Material examined Holotype CHINA ��� ♂; Yunnan, Dali, Yunlong County, Tianchi; 25.854158�� N, 99.239927�� E; 2933 m a.s.l., 14���28 Jun. 2020; You-Jing Gong leg.; MT; SCAU 3042343 (SYSBM). Paratypes CHINA ��� 1 ♂; Yunnan, Dali, Mt Cangshan; 25��41���16��� N, 100��8���33��� E; 25 May 2009; Jie Zeng leg.; SCAU 3040717 (SYSBM) ��� 1 ♂; Dali Dist., Mt Cangshan, 25.66723�� N, 100.14762�� E; 2300 m a.s.l.; 31 May 2020; MT; SCAU 3042339 (SYSBM). Description Male Fully winged (Fig. 7A); length 2.0 mm. Head black, except mandible testaceous; antenna brown-black; mesosoma and metasoma black; fore and mid leg yellow, except club of femur brown; hind leg yellow, except part of coxa, club of femur and tibia brown. Antenna filiform, with setae about as long as breadth of antennomeres; antennomeres in following proportions: 5:5:5:6:6:7:7:7:7:10; length/breadth ratio of ninth antennomere: 7:2. Head (Fig. 7C���D) dull, granulate; frontal line incomplete, present only in anterior half of frons; POL = 5; OL = 3; OOL = 3; OPL = 2; TL = 3; greatest breadth of lateral ocelli about as long as OPL; occipital carina complete. Mesoscutum (Figs 7B, F) dull, granulate. Notauli complete (Fig. 7B) or nearly complete (Fig. 7F), posteriorly separated; minimum distance between notauli slightly shorter than POL (4:5). Mesoscutellum shiny, very slightly granulate. Mesopleuron and metapleuron shiny, unsculptured. Metanotum shiny, unsculptured. Metapectal-propodeal disc reticulate rugose; propodeal declivity with two longitudinal keels and median area shiny, unsculptured. Fore wing hyaline, without dark transverse bands. Distivolsella in form of long straight rod (Fig. 8D); basivolsella long and narrow, with two medial bristles and distal apex very widened (Fig. 8D); distal apex of aedeagus not tridentate (Fig. 8D). Tibial spurs 1/1/2. Female Unknown. Remarks The distivolsella in the form of a long straight rod indicates that the new species is different from all known Aphelopus species, except A. serratus Richards, 1939, from the Palaearctic region. However, in A. zaifui Olmi, Chen & Liu sp. nov. the basivolsella has a widened apex (Fig. 8D), whereas in A. serratus it has a slender apex (Fig. 8F). Following the description of A. zaifui Olmi, Chen & Liu sp. nov., the key to males of Oriental Aphelopus published by Xu et al. (2013) should be modified by replacing couplet 1 as follows: 1.
